Move the in-cab pump shift control valve from the ROAD position to the
PUMP position. The shift warning lights illuminate in a second or two, indi-
cating a complete shift. (See Figure 3-1: “Driver’s Compartment Indicator
Lights” on page 28.)
Notes: If the truck manufacturer has used another in-cab valve to achieve pump shift
or offers an electric switch, follow the instructions supplied with that valve.
CAUTION !
DO NOT LEAVE THE CAB OR ATTEMPT TO PUMP UNTIL ALL THE GREEN PUMP
LIGHTS IN THE CAB AND PANEL ARE ON.
DO NOT OPEN THROTTLE UNLESS ALL GREEN PUMP INDICATOR LIGHTS ARE
ON. (SEE FIGURE 3-2: “PUMP OPERATOR’S PANEL” ON PAGE 29.)
5. Exit the driving compartment only after all the above steps are completed
and you are sure that the shift completed lights in the cab and panel are
ON.
6. Verify that the pump panel shift indicator OK TO PUMP green light is ON
and that all hose connections are complete.
7. Open the tank suction valve.
8. Check the master discharge gauge to see if priming is necessary. If neces-
sary, start the priming pump by pulling the control handle located on the
pump panel or depressing the prime push button.
CAUTION !
IF DISCHARGE GAUGE READING DOES NOT INCREASE, THE INTAKE GAUGE
READING DOES NOT FALL BELOW ZERO, OR THE PRIMING PUMP DOES NOT
DISCHARGE WATER TO THE GROUND WITHIN 30 TO 45 SECONDS, DO NOT
CONTINUE TO RUN THE PRIMING PUMP.
STOP THE PUMP AND CHECK FOR AIR LEAKS OR POSSIBLE PROBLEMS. SEE
SECTION 5 “TROUBLESHOOTING,” ON PAGE 59.
9. Open the engine throttle gradually until the desired pressure or flow is
achieved.
As the throttle is opened, the pressure gauge reading increases with the
engine speed. If the engine speed increases without an increase in pres-
sure, the pump may be cavitating. Also see Section “Appendix F: Cavita-
tion” on page 121.
